VALVE MECHANISM jFOR STEAM-PUMPS.

SPECIFICATION forming part of Letters Patent'No. 503,883, dated August 22, 1893.

Application iiled March 8 1893.

' To 'all whom it may concern:

Be it known that we, JOHNW. TEMPLIN, of Marion, in the county of Grant, and JAMES L. l TEMPLIN, of Kokomo, in the county of Howard, State of Indiana, have invented new and useful Improvements in Valve Mechanism for Steam-Pumps; and we do hereby declare the following to be afull, clear, and exact description of said invention, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of our invention is to produce a valve mechanism for steam pumps and engines, which will automatically and quickly adjust the valves so that the water or steam will be suddenly reversed in order to entirely` prevent liability of stopping on the dead` center.

Further objects of our invention are to improve various details of the mechanism as hereinafter described.

To these ends our invention consists in the construction and combination of parts as hereinafter described and claimed.

In the drawings which accompany and form part of this specification, Figure lis a side elevation of a steam cylinder and a pump cylinder arranged end to end, and showing so much of the construction of the same as is necessary to illustrate our invention. Fig. 2- is a side elevation of the steam cylinder and valve mechanism, looking from the side opposite to that shown in Fig. 1. Fig. 3 is a perspective sectional view of the steam cylinder and valve mechanism, from the side shown in Fig. l, the parts being shown separated to more clearly illustrate the ports; and Fig. 4:- is a detail section on line 4-4 of Fig. 3. Fig. 5 is a detail view showing the connection of the pump valve shaft with its operating rod.

Similar reference letters indicate the same parts throughout the several views.

A and B indicate respectively, the steam and pump cylinders, and A the piston of the latter which connects through rod a', with the piston of the pump cylinder (not shown). The rod c is mounted to have a short sliding movement parallel with cylinderA and has at each end a pin c', the said pins being passed Serial No. 465,109. (No model.)

through the heads of the cylinder and adapted to slide therein and be operated upon by the piston A at each end of its stroke so that the rod c will be given a short reciprocating movement. The pins c' will have suitable packing where they pass through the heads of the cylinder.

Above the cylinder A is a valve chest d containing the rotary valve d', the said chest having the steam inlet d2, exhaust d3 (which may be connected to carry the exhaust steam to any suitable point) and the ports d4 and d which connect with the ports @zand as of the cylinder. The rotary reciprocating valve d is adapted, as is usual with such valves, to

reverse the direction of movement of the live and exhaust steam.

`Above the valve chest d is a smaller valve chest e having a passage way to be connected with the pipe for supplying live steam, and having also a cylindrical seat for a rotary reciprocatingvalve e2 which controls the passage of steam through ports and passage ways similar to those shown in chest d but said ports extending upward instead of downward. These ports in the chest e connect with a small supplemental steam cylinder f which is bolted Vor otherwise secured above said chest e. The inlet e for live steam has passages therefrom to the seat of the valve e2 and to the inlet d2 of valve chest d so that steam may be supplied from one point of connection, in both directions, to the two cylinders. The supplemental steam cylinder f has its piston rod f provided with a yoke bar f2 to which are adjustably secured as by set screws, two collars f3. On the rod c, which is operated by the piston a are adjustably secured two collars c2. The rotary reciprocating valve d has its axis at one end supported by a tapered or pointed screw d6 which passes through the valve chest, and from the opposite side of the said valve a stem thereof extends out from the chest and has connected to it an arln di' which passes between and is operated upon by the collars f3 carried by the yoke bar f2 of the supplemental cylinder. The valve e2 may be similarly supported and its stem is provided with an arm e3 the end of which passes between and is operated upon by the collars c2 on the rod c. The yoke bar f2, at its end to- IOO ward the pumpcylinder has-a rigid-*arm* gextending downwardlyto af-point`in linelwith the axis of valved and to the lower endof this arm vis hingedly connected a linker connectinp,r bar g' the opposite end of which is secured jbyfa elagmpingiserew or otherYg-snit-f able means-1in aslotformed@4 .ina .bar h( s.ee- Fig. 5) which extends inoppositedirections.-5 from the stem h of the rotary reciprocating valve which controls".rtheipassage ,ofwater: through the pump cylinder. f The valve of the pump cylinder is preferably of the same con# struction as .the .-yalve df above .describedyand the object ofthe connection of thelinkgas above described, is to enable thedirectionlfdf the pumpingacti on ofthe pump to be quickly theoppositeendof tithe -barh.
